SPINNING OR WINDING MACHINE.

Application filed January 11, 1921.

T 0 all Q0172 0172 it may concern:

e it known that I, ALoNzo E. RHoADns, a citizen of the United States, residing at Hopedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Spinning or \Vinding Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to spinning or winding machines which are adapted to build up a yarn package or wind yarn upon a yarn recever, that the yarn may be subsequently withdrawn from the yarn receiver by draft lengthwise or axially thereof. More specifically the invention relates to the builder mechanisms whereby the yarn is laid upon the yarn receiver to constitute a preliminary winding or bunch, and thereafter the winding is continued in substantially conical layers toward the end of the reciver.

In machines of this general type, the yarn receiver and the yarn guiding means are given a relative movement in a direction longitudinally of the receiver during the continuous rotation of the latter. This relative movement is generally known in the art as the traverse. In order that the yarn may be properly withdrawn from the receiver in a direction of the longitudinal axis thereof, the traverse is progressively shifted along the axis of the yarn receiver and such relative shifting of the receiver and yarn guiding means is generally known as the gain.

It has been common heretofore to provide a yarn receiver with preliminary windings or a bunch which may be subsc quently utilized to effect a change in the operation 01"- a 100m during the weaving of cloth. In such prior cases, however, it has been the usual practice to wind the bunch and then pass at once from the bunch building traverse to the regular or service traverse. This abrupt change in the traverse has been the cause of breaking down of many ends during the winding operation, and in some cases, has produced undesirable formation at the base or" the wound yarn package or bobbin.

ture of the present inbuilder mechanism for spinning or winding machines wherein the bunch is formed by a bunch building traverse which gradually increases from a minimum to the regular traverse which is thereupon continued throughout the rest of the operation of building the yarn package or bobbin by the regular traverse without any abrupt change.

11 carrying the above feature into practical effect the present invention provides connection between the builder arm and the yarn guiding means which includes two flexible portions or clia connected to mechanism for letting back on both ins, both of which are on the builder arm said chains during the bunch building operation, and further mechanism for modifying the relative movement of the yarn guiding means and yarn receiver so that the yarn will be laid upon the receiver with a minimum and gradually increasing traverse for the bunch building purposes which merges into the regular traverse at the conclusion or completion of the bunch.

providing a yarn receiver windings or a bunch with preliminary and merging the bunch building traverse into the regular traverse without abrupt down the ends.

change which might break Further ob]ects and purposes of the invention will hereinafter appear from the fol] owing description and accompanying drawings which disclose one good, practical form of the invention.

In the drawings 2- Figure 1 IS a perspective view showing sufficient portions of a ring spinning frame with the present invention applied thereto to make clear its construction and mode of operation;

Fig. 2 is an on] showing the two chains or of the connection between and the arged detached detail flexible portions the builder arm yarn guiding means, the let-back mechanism, the deflector, the traverse gaining device, and the compensating mechanism, the parts being in the position they occupy on starting to build the bunch;

Fig. 3 is a view of similar character to that of Fig. 2, with the parts in the position they occupy when the bunch building traverse has been merged into the regular traverse at the completlon of the bunch;

Flg. 1 18 a detached plan vlew show ng the chain guiding and traverse gaining device Fig. 7 is a sectional view on the line 77 of Fig. 6;

Figs. 8 and 9 are detached detail views showing in plan and side elevation respectively, the compensating device between the chains and the yarn guiding means; and

Fig. 10 is a diagrammatic view showing a bobbin having the yarn wound thereon in accordance with the present invention.

The present drawings show the invention associated with a ring spinning frame by which the yarn is twisted andprogressively wound upon the continuously driven yarn receivers, but it is to be understood, of course, that such showing and association of the invention is for illustrative purposes and that the invention-may be applied to other forms of yarn winding machines, though in some respects it is especially adapted to ring spinning frames.

The machine frame is of a character to support the operating parts, and inthe present instance comprises the end frames 1, only one of which is illustrated in Fig. 1. An operating roller or drum 2 (sometimes referred-to as the tin roller) is mounted on the machine frame and through the belting connection 3, Fig. 1, drives a series of spindles, as usual, on which the yarn receivers or bobbins are mounted.

The spindles are supported upon the usual spindle rail 4 which is secured to the machine frame, and above the spindle rail 4: is the ring-rail 5 which usually has a number of yarn guiding means supported thereby. These, in the present instance, are constituted by the rings 6 and travelers 7 only one of such rings and travelers being indicated in the drawings. The'yarn a is taken from a source of supply and passes through the traveler 7 by which it is guided to the yarn receiver or bobbin on which the yarn is wound. i

The ring-rail 5 has extending downwardly therefrom the rod 8, the lower end of which has a foot-piece 9 resting upon a roller or other bearing 10 carried by the arm 11 of a lever which is pivoted on the machine frame as usual. The other arm 12 of the lever in the present instance of the invention, has a segment portion13, and the lever constituted by the arms 11 and 12 is normally under the influence of a weightle which tends to left the ring-rail. These parts are as usual in a ring spinning frame.

The builder arm 15 is .pivotally supported on an axis 16 by the machine frame in the usual manner, and is provided with a weight 17 which normally tends to hold the roller 18, projecting from the builder arm, in operative relation with the builder cam 19. The builder cam will be driven as usual, from an appropriate source of power, but

since the builder arm and its relation with the builder cam. and the operating means for the builder cam are all old and well known, further detailed description and illustration of these features are not needed.

The builder arm 15 has mounted thereon a let-back mechanism which is driven as usual in this class of machines, through a pick-wheel 20 and the-operating pawl 21 carried by the depending arm 22, the upper end of which is secured to the frame of the machine at 23. The pick-wheel 20 is secured to the pick-wheel shaft 241- which is mounted for rotati've. movement in the bearing 25 carried by the builder arm. The pick shaft 24 has the worm 26 which is in operative engagement with the worm wheel 27 of the let-back mechanism. These parts are all of usual character as shown in the present instance of the invention, andfurther description of these features will not be necessary.

The present invention provides connections between the builder arm 15 and the yarn guiding means or ring-rail 5 which include two flexible portions or chains which are separately connected to the let-back mechanism so that they may both be let-back during the operation of the builder arm; and between the let-back mechanism and the yarn guiding means or the ring-rail5, means is provided for modifying the action of the chains upon the yarn guiding means or ringrail to elfeet the building of a bunch by a bunch-building traverse which is gradually merged into the regular traverse without abrupt change in the extent of traverse.

The worm wheel 27 which constitutes part of the let-back mechanism,- is mounted upon a stud 28 carried by the builder arm 15 and has a hub portion 29. The let-back mechanism has secured to it a deflector whiclnas will hereinafter more fully appear, is for the purpose of deflecting one of the chains and causing it to let-back faster than the other chain, and to finally slacken the chain on which it operates to enable regular traverse wind to be effected through the other of said chains. r

In the present instance, the deflector is constituted by an arm 30 mounted'on the projecting hub portion 29 of the worm wheel 27 and secured thereto by means such as the pins 31. The pins 31 prevent relative movement of the deflector 30 and the worm wheel 27 and the deflector is conveniently held in associated relation with the worm 27 means of a nut 32 on the end of the stud 28.

The two chains which constitute the flexible portions of the connection between the builder arm and the yarn guiding means or ring-rail, may be conveniently formed in two parts, although this detail is not essential. n the present instance one of the chains 33 is connected to the let-back mechanism by the pin 34, and the other chain 35 is connected to the let-back mechanism by the pin 36 and then such chain 35 passes about the deflector 30 as indicated in Fig. 1, the construction being such that when the builder arm is operated and the let-back mechanism is ac tuated through the pick-wheel, as usual in this class of machines, both the chains 33 and 35 will be let-back, but the chain 35 will be let-back faster than the chain 33 due to the action of the deflector.

A bracket 37 is secured to one of the end frames of the machine for supporting the guide pulley for one of the chains and the traverse gaining device of the other chain. In the present instance, the arm 37 has the open bearings 38 in which are received the end portions 39 of a cylindrical barrel 40 which is preferably formed as part of the traverse gaining device. The traverse gaining device is formed by a. cylindrical member 41 and a slabbed-ofi or segmental member 42. Between the member 41 and one of the bearings 38, the guides 43 forone of the" chains are mounted upon the cylindrical barrel 40 of the traverse gaining device. The construction is such that the guides for one of the chains may rotate independently of the traverse gaining device 41, 42.

The chain 33, which for purposes of identification may be called the regular traverse building chain, extends from the let-back mechanism and is secured at 44 to one of the guides 43, Fig. 2. Secured at 45 to the other of the guides 43 is the completing portion 33 of the regular traverse building chain 33.

The other chain 35, which for identification may be known as the bunchbuilding chain, extends about the deflector 30 and is secured at 46 (F ig. 2) to the part 41 of the traverse gaining device. The complemental portion 35 of the bunch builder chain 35 is secured at 47 (Figs. 2 and 5) to the slabbedofl member or segment 42 of the traverse gaining device.

Each of the two chains which constitute part of the connection between the builder arm and the yarn guiding means or ringrail, is, as above described, preferably formed of two portions, but in some instances, it desired, each of these chains may be continuous. In either event, the ends of the chains remote from the builder arm are associated with a compensating device which, in the present instance of the invention. comprises a rocking member or lever 48 (Figs. 2, 3, 8

and 9) pivoted at 49 to a bar or arm 50 which is itself connected to the ring-rail-operatinglever ll, 12, through the segment portion 13 thereof, as indicated in Fig. 1.

The rocking member or lever 48 may be conveniently formed with the two hooks 51 and 52 to which the respective chains 33 and 35* may be secured by I-pieces 53, 54, Figs. 1 and 2.

he hooks 51 and 52 are connected to the rocker 48 at points differently distanced from the pivotal connection 49 of the rock ing member with the arm 50, as indicated in Figs. 2,3 and 8, and the rocking member has a stop 55 which is adapted to engage a complemental stop 56 carried by the arm 50 under conditions as will presently appear.

In starting the winding operation, the parts are placed in the position indicated in Figs. 1 and 2. In this position of parts the initial winding or bunch, as indicated in Fig. 10, will be started on the yarn receiver or bobbin 57 at the base 58, due to the maximum deflecting action of the deflector 30 upon the bunch building chain 5 and the position of the traverse gaining device. As the bunch builder arm is given its oscillatory movements by the bunch building cam as usual, and the pick-wheel is actuated through the train of mechanism hereinbeiore described, the let-back mechanism will be operated to let-back on both the regular traverse and bunch builder chains 33 and respectively; and the let-back action on the bunch building chain will be faster or greater than that of the regular traverse by reason of the deflector 30. This difi'erential let-back action upon the chains 33 and 35 is further modified by the traverse gaining device, and both chains are caused to function through the compensating device during the bunch building operation. As the let-back mechanism continues to let-back on the successive oscillations of the builder arm, the deflector and traverse gaining device gradually change from the position iudicated in Fig. 2 to that indicated in Fig. 3, thereby gradually merging the bunch building traverse into the regular traverse, until finally, when the regular traverse is reached, as indicated by the position of parts in Fig. 3, the bunch building chain will be slackened and the regular traverse accomplished through the regular traverse chain. At such times it will be noted, that the stops 55, 56 are engaged, Figs. 3 and 8,. and remain in engaged position throughout the winding operation until the yarn receiver has had wound upon it its complete load of yarn. Under control of the above described train of mechanism, the yarn guiding means or ring-rail will start the bunch building operation by a traverse of mini mum extent, and will gradually increase the traverse and also the gainof traverse until arm, a builder cam for operating the traverse gradually merges into the regu-- lar service traverse, and the gain of traverse merges into the regular service gain..
